ATTRIBUTE BASED SECURE DATA SHARING SCHEME WITH EFFICIENT REVOCATION IN CLOUD COMPUTING

In recent days, the cloud computing is one of the Attribute based Secure Data sharing scheme with Efficient Revocation (EABDS) is a fine grainedattribute structure. Keywords: Cloud computing. Authorization, Efficient revocation, Data encryption key, Security analysis emerging field. It is a platform to maintain the data and privacy of the users. To process and regulate the data with high security, the access control meth ods are used. The cloud environment always faces several challenges such as robustness, security is- sues and so on. Conventional methods likeCipher text-Policy Attribute-Based Encryption (CP-ABE) are considered for providing the data security, but still theproblem exists like thenon-existence of at- tribute revocation and minimum efficient. Hence, this research workparticularly discussesvarious fea- tures of attribute based access control mechanismto maximize the efficiency. Initially, an objective coined out in this work is to definethe attributes for aset of users. Secondly, the data is to be re-encrypted based on the access policies defined for the particular file. The re-encryption process renders information to the cloud server for verifying the authenticity of theuser even though theowner is in offline. The main advan tage of this workevaluates multiple attributes and allows respective users who possess those attributes to access the data.
